COMBINED JAR CAP AND OPENER.

Specification of Letters Patent.

Patented Dec. 1,1908.

Application filed. leptember 10, 1908. Serial No. 2,438.

To all whom it may concern:

Be it known that I, HENRY C. CU'RNOW, a citizen of the United States, residing at Oolumbia,'in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Com bined Jar Caps and Openers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable-others skilled in the art to which it a pertains to make and use the same.

his invention relates to improvements in combined jar caps and openers.

The ob'ect of the invention is to provide a combine milk jar cap and opener whereby the. ordinary pasteboard closing disk may be readily removed and a sanitary, non-corrosive tight-fitting cover provided which may be readily removed from and replaced on the jar when desired. a

With this and other objects in view, the invention consists of certain novel features of construction, combinationand arrangement of parts as will bedescribed and particularly pointed out in the appended claims.

In the accompanying drawing, Figure 1 is a vertical sectional view of the upper end of a milk jar showing my improved cap a plied thereto in osition to remove the paste oard closingdis Fig. 2 is a similar view showing the cap applied to the jar to close the latter; and Fig. 3 is. an enlarged perspective view of the cap.

In t e accompanyin cap, which is formed 0 non-corrosive metal.

drawing, 1 denotes a aluminum or'similar The cap comprises an which conforms to and is ada ted to engaged with the upper edge of t e jar neck, as shown. ,The flan e, 3 is provided with an outwardly-turned ower ed e, 3, which facilitates the e agement wit and disen a eange, 2, from the edge 0 t e jar neck, and also serves to stre hen said edge, and to provide a smooth finish for the same.

The ca 1, is provided with a centrallydepress or downwardlyrojecting portion, 4, which is-ada' ted to t into the annular fioove or recess ormed in the inner edge of t e mouth-of the jar and to rovide a fluid-tight engagement with sai groove, which, to ether, withthe engagement of the up er en of the jar neck, forms a double sea or closure for the jar.

Secured to the center of the depressed porquirin tion, 4, of the cap and projecting downwardly a suitable distance therefrom is a prong or barb, 5, having a triangular arrow-shgped head, 6, said prong or barb being ada t to 'be forced through the pasteboard isk, 7, which is usually employed for temporarily closing milk jars or bottles after being filled for delivery. The pron or barb is forced through the pasteboard isk by the engagement of the cap, 1, with the up or end of t e jar neck, as clearly shown in l 'ig. 1 of the drawing, after which the cap is pulled ofi the neck of the jar, carrying with it the pasteboard disk, 7,.the cap thus forming a convenient means for removing said disk. After the disk has been thus removed from the jar, it is disengaged from the barb or prong, 5, and the cap then replaced upon the neck of the jar to serve as a cover therefor.

The cap is preferably formed of aluminum, but may be constructed of any non-corrosive metal, and is preferably ofsuch thickness as to provide sufiicient elasticity or yielding ualities to the flange, 2, thereof, to permit t e latter to be s rung into and out of engagement with t e rounded outer edge of the jar neck, said cap thus forming an eflicient closure for the jar which may be readily engaged with and disengaged therefrom when desired.

From the foregoing description, takenin connection with the accompanying drawing, the construction 'and operation of the invention will be readilyunderstood without rea more extended explanation. Various changes. in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. A device of the class described comprising a metallic cap having a centrally depressed dportion to fit into t e mouth of the ar, an an annular flange to engage the outer edge of the 11 per end of the ar neck, and means carried p pasteboard closing isk of t 0 jar to ac1l1- tate the removal thereof.

2. In a combined jar cap and opener, a cap having a centrally depressed closing portion adapted to be e aged with and seat in the open end or mout of the jar to form an sai'd ca to enga e the" inner closure therewith, and an annular In testimony whereof I have hereunto set downwardly-projectingresilientflange adaptmy hand in presence of two subscribing 10 ed to his sprfunfi; into engafemefitwith till: w tnesses. outere eo t eu eren 0ft e 'arnec 5 and a baii'b carded-b said cap and adapted HENRY CURNOW' to be forced through-and thereb connected Witnesses: with the pasteboard closing dis of the jar JJE.
